Finally, OSCAR expression was positively correlated with infiltrating levels of M2 macrophages in 20/20 types of cancer, especially BLCA (CD163, r=0.767, VSIG4, r=0.761, MS4A4A r=0.753), COAD (CD163, r=0.717, VSIG4, r=0.726, MS4A4A, r=0.695), and THCA (CD163, r=0.698, VSIG4, r=0.782, MS4A4A r=0.787). Here, MS4A4A is linked to cancer.
